This invention relates to a device for supporting battles betweenvertically disposed tubes and by means of the tubes, so as to preventthe saine from slipping longitudinally of the tubes. rlhe invention willbe understood from the description in connection with m the accompanyingdrawings, in which:

Fig. 1 is a vertical section through a boiler illustrating anapplication of the invention.

F ig. 2 is a fragmentary elevation ot a tube showing a preferred formfor supporting the baile thereon.

Fig. 3 is a View taken at right angles to Fig. 2, but with the balileremoved.

Figs. 4 and 5 are views taken on the lines 7-7 and 8-8 respectively, ofFig. 3.

In Fig. 1 is indicated a boiler of the Stirling type in which the muddrum is shown at 8, and the upper steam andwater drums at 9, 10 and 11,the drums being connected by banks of tubes, as shown at 12, 13 and 14,and battles are provided in the usual way. rl'he two baffles 15 and 1G,as shown in this figure. need to be supported to prevent the same lfromslipping downwardly, and supports made in accordance with my inventionare shown ytherefor at 17.

The baille support shown in Figs. 2 to 5 comprises a. clamp 23 ofU-shape, engaging a tube 13 and having a bolt 24 passing through theends of the clamp which, in this illustration, is shown as a strap.ldetween the bolt and the tube is disposed a wedge 25 having a recess inone face to iit the tube, thereby providing extended thermal contact. A.suitable thimble 26 may be placed around the bolt it desired.

Resting on the wedge 25 is a bearing member 27, here shown as an anglebar adapted to support the baille 15. lf desired, the bearing member maybe independently held against the tube by means of a clamp 28 here shownas a U-shaped rod with ends on which are threaded nuts 29. lf desired,the clamp 23 may be spot welded to the tube, as indicated at 30.

l claim 1. In a boiler, a row of water tubes having abaie disposedadjacent thereto, a clamp surrounding one of said tubes, a wedge betweensaid clamp and tube, and a bearing member iesting on said wedge andadapted to support said battle thereon.

2. In a boiler, a row of water tubes having a baffle disposed adjacentthereto, a clamp surrounding one of said tubes, a wedge between saidclamp and tube, a bearing member resting on said wedge and adapted tosupport said battle thereon, and meansto hold said bearing memberagainst said tube.

3. ln a boiler, a row of water tubes having a baiile disposed adjacentthereto, a U-shaped strap engaging one of said tubes, a bolt eX- tendingthrough the ends of lsaid strap and adapted to tighten the strap on thetube, and a wedge disposed between the bolt and tube and adapted tosupport said baille, with the wedge face extending parallel to thelength of the tubes.

1. In a. boiler, a row of water tubes having a baille disposed adjacentthereto, a U- shaped strap engaging one of said tubes, a bolt extendingthrough the ends of said strap and adapted to tighten the strap on thetube, a wedge disposed between the bolt and tube and adapted to suportsaid baffle, and a bearing member disposed between said baille andwedge.

5. In a boiler, a row of water tubes having a baiiie disposed adjacentthereto, a U-shaped strap engaging one of said tubes, a bolt eX-teiiding through the ends of said strap and adapted to tighten the strapon the tube, a wedge disposed between the bolt and tube and adapted tosupport said baliie, a bearing meniber disposed between said battle andwedge, and means to clamp said bearing member against said tube.
